On a well-maintained Linux system, months can go by without needing to reboot. Sooner or later, however, a security patch to the Linux kernel will require you to reboot your machine. That's not a real problem on a desktop, but when you're talking hundreds of servers it can be a real pain. That's where CloudLinux's new program KernelCare comes in.
CloudLinux, makers of the CentOS-related CloudLinux OS, a Linux distribution for hosting providers, claims that with KernelCare, scheduled outages for security patches on Linux servers are now a thing of the past, giving organizations real-time updates. The program automatically applies Linux server security updates without having to re-boot. This frees technical personnel from the laborious process that takes several minutes for every server, several times a year.
